BUILDING BLOCK.

Application filed November 14, 1923. Serial No. 674,648.

To all whom it may concern:

Be it known that I, RICHARD MURRAY, a citizen of the United States. andresiding at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Building Blocks. ofwhich the'following is a specification, such as will enable thoseskilled in the art to which it appertains to make and use the same.

This invention relates to building bricks or blocks used in theconstruction of comparatively small buildings; that is to say, buildingsof one, two or three story height, and the object of the invention is toprovide a building brick or block of the class specified, which is soconstructed as to form the entire or complete wall of a building and toprovide finished inner and outer faces for such wall or walls, a furtherobject being to provide a brick or block composed of two differentgrades of material with means for binding the separate materialstogether, one of the materials employed forming the outer face of thebrick or block, and the other, the inner face thereof; a still furtherobject being to provide a hollow brick or block of the class specified,whereby the construction thereof will provide a comparatively light andyet strong and durable brick or block, and also whereby the cost ofproduction or manufacture thereof is materially reduced, the periphery"of the brick or block being also provided, if desired, with a groove tofacilitate the interlocking of ad jacent bricks or blocks; and withthese and other objects in view, the invention consists in a brick orblock of the class and for the purpose specified, constructed ashereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are deslgnated by suitable reference characters ineach of the views, and in which Fig. l is a perspective view of one formof block made accordin to my invention.

Fig. 2 is a longitu inal sectional view through the block shown in Fig.1.

Fig. 3 is a View similar to Fig. 1 showing a modified form of block;and,

Fig. 4 is a plan view of a block similar to that shown in Figs. 1 and 2but showing a modification.

In Figs. 1 and 2 of the drawing, I have shown at 5 one form of brick orblock 5 made according to my invention, said block being oblong andrectangular in form. In constructing the brick or block, I provide twobox-shaped core pieces 6 which are rectangular in form and composed ofinexpensive material, such for example as cardboard or the like, andthese core pieces are imbedded in the brick or block in its formationand are spaced apart to provide in the completed brick or block.chambers 7.

Surrounding the core pieces 6 and 7 is a body of concrete, cement or thelike 8 and a body of plaster or plastic composition 9, these bodiesbeing joined together by a body 10 composed of long strands of fibrousmaterial, hair or the like, into which the material of the separatebodies 8 and 9 is imbedded and saturated as will be apparent. The body 8constitutes the outer face of the brick or block and extends throughsubstantially two thirds of the depth of the brick or block, while thebody 9 constitutes the inner face of the brick or block and is adaptedto form or provide a finished inner face for the wall or walls of abuilding.

In the construction shown in Figs. 1 and 2, the periphery of the brickor block 5 or the top, bottom and end walls thereof are provided withinterconnnunicating grooves 11 which are adapted to function as meansfor keying adjacent bricks or blocks together, said grooves providingmeans for receiving key pins or bars, or for receiving mortar, cement orthe like in the construction of a wall.

In Fig. 3 of the drawing, 1 have shown a brick or block 12, which isrectangular in form and within which is a single core piece 6, the block12 being constructed in precisely the same manner as the construction ofthe block 5 shown in Figs. 1 and 2, but provided with the separatebodies 8, 9 and 10 forming finished outer and inner faces 8 and 9, itbeing understood that the block 12 is substantially one half the size ofthe block 5, and the grooves 11 have been omitted, as it is notabsolutely necessary that these grooves be employed. In Fig. 4 of thedrawing I have shown a block similar to that shown in Figs. 1 and 2 bothin shape, and construction, the only difference being that the grooves11 have been omitted.

By constructing a brick or block as herein set out, I provide acomparatively light brick or block and yet one which has the.

required strength for the use for which it is intended, for example inthe construction of comparatively low buildings, and further it will beapparent that my improved brick or block, or after a number of saidbricks or blocks have been assembled in the construction of the walls ofa building, will provide finished inner and outer faces for such walls,the outer face being a concrete or cement composition, while the inner,a plastic facing, and by using my improved brick or blocks, theconstruction of the walls of a building is materially simplified, andthe cost of material reduced, and also effecting a decided saving in thetime and labor in the construction of a building.

It will be understood that I am not necessarily limited to the use ofany specific number of core pieces 6, nor to the specific shape thereofherein shown and described nor am 1 limited to any specific combinationsof materials in the construction of the brick or block, and variouschanges in and modifications of the construction herein shown anddescribed may be made within the scope of the appended claims, withoutdeparting from the spirit of my invention or sacriticing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A brick or block of the class described composed of two differentbodies of material, one of said bodies forming one face of the brick orblock, and the other the other face thereof, one of said bodiesextending through the greater portion of the depth of said brick orblock, and a body of binding material for joining the separate bodiestogether, said last named body being composed of long strands ofirregularly arranged fibrous material.

2. A brick or block of the class described composed of two differentbodies of material, one of said bodies forming one face of the brick orblock. and the other the other face thereof, one of said bodiesextending through the greater portion of the depth of said brick orblock, a body of binding material for joining the separate bodiestogether, said last named body being composed of long strands ofirregularly arranged fibrous material, and said block being hollow.

3. A building block of the class described composed of two differentmaterials, one of which forms one face of the block, and the other thebody portion and remaining face thereof, means for binding said materialtogether to form a unitary block, a hollow core piece embedded in saidblock. the inner face of said core piece being substantially in the sameplane as the inner portion of the facing material, and the binding meansextending rearwardly of said face portion of the core member.

In testimony that l claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 10th day of November,1923.

RICHARD MURRAY.
